MA plans use a health assessment to collect that information, usually when someone first enrolls in a plan via a “Welcome to Medicare” office visit. Critics say Medicare Advantage plans are pushing home visits in order to find more diagnoses that can increase member risk scores and resulting payments from Medicare regardless of whether they treat those conditions. Using chart reviews and HRAs to increase payments from Medicare without providing or improving care for those diagnoses is called “upcoding,” and it can result in overpayments and improper payments by Medicare.
